Outline a complete mechanistic sequencefor the reaction of 2-bromobutane with potasium2-methyl-2-propoxide in 2-methyl-2-propanol solvent to form thethree alkenes generated in the reaction (1-butene, trans-2-butene,and cis-2-butene). Include a clear drawing of the anti-periplanartransition state for the formation of each alkene.
Determine the Keq for the reaction of benzoic acid with 4-nitroaniline.
Calculate the wavelength of light that would be required to excite an electron from the HOMO to the LUMO. Hint: Recall that (triangle)E=hv=hc/lambda, and that 1 eV=1.602 x 10^-19 Joules.
If a minimum energy of 2.00x10^5 J/mol is needed for this process, what is the minimum energy needed from each photon? B. Calculate the wavelength of light necessary to provide photons of this energy
